To all whom 1' 2 may concern:

Be it known-that 1, GlUsEPPE Rocco, a subject of the Emperor of Austria-Hungary, residing at Trieste, Empire of Austria-Hungary, have invented certain new and useful improvements in Acetylene-Generators; and I do hereby declare t-he'following to be a full, clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to acetylene lighting apparatus and more particularly to intermittent light apparatus for sea lights.

in the apparatus constructed in accordance with my invention calcium carbid is automatically introduced in predetermined quantities'into water whenever the quantity of acetylene in the gasholder is reduced to a predetermined *minimum. The gas flows from the gasholder through a wet gas meter into two tubes, one of which is provided with an adjustable throttling device and the other witlr a valve or equivalent device opening and closing alternately at and for predetermined intervals, the two tubes lead to a pipe supplying the burners of the intermittent sea light. The throttling device in one of the tubes permits to flow to the burners a quantity of gas which is just sufficient to kee burning small flames which are not visiile at a greater distance, whereas the valve or equivalent closing device in the other tube. when 0 en, permitsso large a quantity of gas to ow'to the burners that the flames are greatly increased and thereforethe light becomes very intense and visible at great distances. In this way an intermittent light is obtained. The closing device is alternately opened and shut by a mechanism the movement of which is governed by a pendulumfand which is driven by the wet gas meter;

In the accompanying drawings, Figure 1 shows diagrammatically the arrangement of the apparatus as a whole. Fig. 2 1s a verti cal section of the apparatus for intermittently introducing calcium carbid into the acetylene generator. Fig. 3 is a view similar to Fig. 2 showin tion, and Fig. 4 s

introducm apparatus in elevation.

I bolder raising the bell of the latter; the lever the parts in another posi-' upper end of the pipe "ects above the water is covered by a cap 2 which slightl prolevel in the gas 10 der 4, the lower edge of which is below the water level so that. gas can 0 escape from the ipe into the gas holder but no gas can flow liack from the gas holder to the gas generator.

5 is a pipe .rmitting the gas to flow from the bell ofthe gas holder to below such bell. 7 is a pipeleading the gas from such chamber to a purifier 8 from which the gas flows through a pipe 9 to a wet gas meter 10 of any known or suitable con- 1 l and 12 are two pipes through which the gas flows from the gas meter to a leading directly to the burners 1 1. A cord or chain 15 is attached with one end to the upper part of the bell runs round a loose. guide pulley 16 journaled in the gas holder framing. The other end of this cord or chain is attached to a weighted lever 17 pivoted on the gas generator 1 and actuating the mechanism introducing calcium carbid into the gas generator.

When the gas holder bell has sunk beyond a predetermined limit the lever 17 is raised by the cord or chain of carbid to be introduced into the, genera- The as then evolved flows to the gas 17 is lowered being Wei hted and the carbid feeding mechanism of t 1e gas generator is returned mto its initial position. When owing to an abundant-production of gas the gas holder bell is raised beyond a predetermined limit it opens an escape device, for instance a cock 20 in a pipe 21 communicating with the gas chamber 6, whereupon the excess of gas escapes into the atmosphere. Fig. 1 the mechanism for operating the escape device or cock 20 consists of a length of rack 18 secured to the gas-holder bell and adapted to engage into a toothed segment 19 attached to the cock 20 whenever the bell ris'es beyond a redetermined point.

he mechanism for intermittently introducing calcium carbid into the water in the gas enerator 1 is shown in Figs. 2 to 4. It consists of a slide 22 working in a casing 23 fixed air tight to the neck 24 of the as generator. For better uiding the slide 22 in the casing a loose rol er 25 frame 26 mounted in the slide 22 and springs 27 are interposed between the back wall of a gas chamber 6 5 pipe 13 of the gas holder and 75 for intermittently 8Q 15 and causes a fresh charge 85 As shown in 1s journaled in a i the slide andof the spring 33. i

the slide and the. franie carrying the roller 25 whereby the roller is held in contact with the. front wall of the casing 23.

The slide is hollow and its front to is provided with an opening which when the slide 7 is in its uppermost position shown in Fi 2 is slide is provided with a pivoted gate or valve 30 having lateral lugs 31 an aging into vertical slots 32 in the casing an with a s ring 33 tending to open the said ate or va ve. i In the u permost position 0 the slide the gate or -va ve is prevented fromopening by the said In s 31 engaging the upper straight pore tions ol the slots 32. When, however, owing to the consumption of gas the gas holder bell sinks below a predetermined limit and consequently the outer end of the lever 17 connected to the cord or chain 15 is raised and thereby the rod 29' is lowered and the slide 22 is brought into the position shown in Fig. 3, the upper full portion 34 of the slide 22 comes opposite the open end of the' funnel 28 thus stopping the flow of carbid from the said funnel to theinteriorof the slide. At the same time the lugs 31 comev into the enlarged or curved portion 35 of the slots 32-thereby ermitting the gate or valve 30 to be opened by the combined action of the carbid Within The carbid is then discharged into the water contained in the generator and acetylene is evolved and flows to the gas holder. The gas holder bell is raised, the lever l7 being weighted raises the slide 22 into the position shown in Fi 2 and the lugs 31 slide along the curved left hand edge 35 of the slots 32 whereby the gate or valve 30 is closed-against the action of the spring 33. The slide is then again charged with carbid as above described and is ready for the next discharge. I,

If it 'is desired to altogether stop the production of gas it is only necessary to lock the rod 29 in its uppermost position by a suitable dog 36 as shown in Fig. 1, the said dog 36 being pivoted on a vertical axis in the frame of the apparatus and adapted to engage below a shoulder on the rod 29.

In order that the gate or valve 30 may be tightly held to the rear wall of the slide when the latter is in its upermost osition weighted arms 36 may be provide which are pivoted to the casing 23 and whichin the.

' uppermost position of the slide bears against the lugs 31 thereby holding them against the rear Wall of the slide.

i As already described the gas passes from the gas holder through the purifier Sand pipe 9 and gas meter 10 to two tubes-11, 12, both of which lead to the tube 13 going-to the burners 14. On'of these tubes 11 contains a throttling device indicated at 11 and of any known or preferred construction which permits only so small a quantity of gas to pass through the tube 11 as is sufficient for kee ing burning small flames that are not visib e at larger distances. The other tube 12 contains an alternately opening and shutting organ such as a valve, which'when open permits to pass through the tube 12 a quantity of gas sufficient for maintaining large flames vislble at great distances.

By properly adjusting the intervals between the opening and shutting periods of the -'said closing organ and by properly adj usting the duration of the opening and shut-- ting periods themselves an intermittent light of-any desired character may be obtained.
